CO and CH4 sensing with single mode 2.3 μm GaSb-based VCSEL

Not Accessible

Your library or personal account may give you access


Successful application of recently developed GaSb-based singlemode vertical-cavity surface-emitting lasers for gas-sensing at 2.3 μm is reported. CO and CH4 have been detected simultaneously using wavelength modulation spectroscopy with a multi-line curve fit concept.
